HAY-LOADER.

Application filed August 1 To o?? whom- [t muy concern.'

Be it known that we, ALEXUS C. Inxoomzx and ORBIN F. SMITH. citizens ot' the United States. residing at Moline, in the county ot' Rock Island and State of Illinois, have iuventedcertain new and useful Improvements in Hay-Loaders, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to hay loaders' ot' the type embodying' a wheeled ele 'ator frame equipped with reciprocating rake bars.v driven from the ground wheels in such manner that as the machine is drawn over the. field in rear of a f"agon the hay will be gathered and elevated by the rake bars and delivered into'the'wagon. It has been proposed in machines ofthis type to drive the rake bars, which are usually ar 'anged in two. groups so as to act alternately. from the ground wheels by opposiielv disposed cranks arranged alongside the wheels. the'cranks beingconnected with the respective groups of rake bars and acting by their rotation to reciprocate the operating levers, and give `the necessary movements to therake bars to gather-'and Aelevate the hay. It is a desideratum in these n'iachines that the 'raking stroke of the rake bars be as long as possible, but the length of the stroke is limited'hy the fact that the driving cranks cannot be longer than the radius of the wheel, otherwise in their rotation they would contact with the'ground. v

AIt is the aim of our invention to lengthen the effective raking stroke of the rake bars in relation to thel length ofthe driving cranks,or as stated in another-way, to enable la shorter vdrivingcrank to be used, without shorteningthe teifective length of Ithe raking stroke.

With' this aim in view lour invention consists in means broadly tor so connecting the operatin levers with the rakebars that the latter wi l', as the levers are operated, move relatively thereto to `lengthen the raking stroke. u w. In the accompanying drawings: Figure 1 is a side elevation of la hay' loader with our invention embodied therein. Fie. '2 is a plan view. of the same. 'Fig 3 is an elevation on an enlarged scale of the rake bar operating mechanism, showing the rake bars at the beginning of their forward raking Specification of Letters Patent.

partially completed the raking stroke. rig. 5 is a similar view showing the position ot' the parts when .the rake bars are, at the forward end of the raking stroke. l Referring to the. drawings: l represents a suitable elevator,:t'ramc, upwardly inclined as usual. and supported by ground wheels 2 4, mounted on an axle A. to which latter is fixed at opposite ends, pairs of oppositel 6E disposed driving cranks 3;-3. 4-4. which cranks are arranged at the outer sides of the wheels. Arranged over theelevator fraaie so as to co'perate therewith, are a lseries of rake bars. arranged in two alter.-

nately acting groups 5 and 6, thefbarsof the group 5 being connected together by a transverse bar 51. while the ,rake bars of the group 6' are likewise connected together by atransverse bar Gn. At its ends the 76 trai'isverse bar 5 is ope atiely connected with operating levers T-T. one on each side of the machine, which operating levers arc in turn connected with the cranks 3-l. wl'iereliy the rotation of thc cranks will 80 operate one group of rake hars. The ends of the transverse har (3 are operatively connected with operating levcrs'S-S, arranged respectivelv alongside the other operating levers. one on each side of the machine, 8 5 which levers are connected at their forward ends' with the other pair of driving cranksl -l-L h v which mechanism the group (i .of rake harsis driven. y

'I` he foregoing parts ma) be of any ap- 90 proved and appropriate construction, asthey in themselves form no part of thel present invention. Our invention is coneerncdwith the. connections between the groups of rake said connections heilig of a character to 'anse the rake bars. when the operatinglevers are V1ecipro'ate.d. to move relativelv to said levers. ,in the ydirection of their re- 10, the upper end of which is lformed with two horizontal outwardly projecting hollow stroke. vFig. 4 is a similar view showing the position of the Vparts' afterf the rake bars have mh 11--11. in which are loosely mounted bars and their respective operating levers. 9b

ciprocation. the result being that the raking 10 ros stroke.

bracket plate is xed to the side of the' elev-` vator frame. The hanger 10 is extended below thev stud 9 and has its lower'extremity pivoted as at 16' to the forward end of a plate 17which extends rearwardly beneath the operating lever to the rear end of the same, where itis jointed on a horizontal transverse axis 18 to the end of a cross bar' 5 of the group of rake bars 5 before alluded to. Nearits rear end the plate is suspended from the end .of the lever by means of a stirrup 19 in suchl manner that the plate may move longitudinally with relation to the lever, as the latter is reciproeated back and forth by the rotation of its driving crank.

Referring to Fig.A 5, the rake bars are shown as "at the forward end of the raking stroke, in which position ofthe parts the links 13-13 are inclined upwardly and forn wardly and the hanger 10 inclined'forwardly and downwardly, with the plate .17 shifted to' its forward position with reference to the operating lever. l/Vhen the crank is now rotated in the direction of the arrow in Fig. 5,

the operating lever will be shifted in a rearward directiornby which motion the links '1S-13 will be swung to the rear and the hanger 10 likewise shifted to the rear. In suoli shifting movement, the hanger will rock on the stud 9 on the lever 7, which rockward movement of vthe lever is completed, shift the plate 17 relative to the lever and longitudinally thereof, the result being that the rake bars will be moved rearwardly and relative to the levers, and in this manner the effective stroke of the rake bars will be' in creased by an amountequal to this relative movement. of the rake bars. The parts are now in the position shown in Fig. 3, the rake bars being at the rear end of the raking Onthe continued movement of the crank in -the direction of the arrow in Fig. 8, the operating leverwi'll be drawn forwardly and the links 13--18 swung in a corresponding direction, thereby carrying the hanger 10 in a forwarddirection and causing the same to rock relative to the lever on v the stud 9, the position of the parts when the' lever has thus partially completed its forward stroke being shown in 4l. in which it' will be seen that the plate 17 has, by the rocking lmotionof thehanger relative to the lever, been shifted forwardly relative to the lever from its extreme rear position of Fig. 3. The further movement of the crank in the direction of the arrow in original position as shown .in Fig.v 5, in which final movement-,the plate 17 will, by the roc-king action of the hanger on the lever,` be shifted lto its lformer extreme .forwardl position relative to the lever. It is seen1`70 theref0re, that by the reciprocating movements of the lever, due to the rotation of its@ drivingcrank, therake bars in moving to the rear lto begin their forward raking stroke, are shifted rearwardly, relative to 7.5

"the lever and in this manner the effective raking stroke is correspondingly lengthened. The operating lever 8 for the other group of rake bars 6 is connected to and operated by its crank and supporting hanger and 30 links, in precisely the same manner as that described, the only difference being that the parts are so related that. the actions of the two groups of rake bars will alternate with each other, one groupnno 'ing forwardly as 35 the other retreats. The lJeverA 8 is mounted between its ends on a stud 20 projecting inwardly from the lower end of a vibrating hanger 2l. the upper end of which is provided with two inwardly7 projecting horizon- 90 Ytal hollow studs 22-22 in which are loosely mounted the upper inwardly .turned endsof links 23 Q3. The lower ends of these links v. are extended horizontally inwardly and mounted loosely in horizontal bearing ,open- 95 ings 21-24 in the opposite ends of the bracketplate 15 .before alluded to. A The lower end of the hanger is extended below its pivotal stud and jointedto the forward end of a shifting plate 25 extending beneath 100 the lever 8 and jointed at its rear end to the connecting bar 6a of the group of rake bars 6, this plate being suspended at the rear end of the lever. by a stirrup 26, similar in construction and arrangement to the stirrup 19 105 already described. .As a result of this mech anism, the group of rake bars 6 will be oper'- ated by its levers 8-8 in a manner similar to 'the operation of the other group, the

plate 9.5 shifting rearwardly relative toi-the 11o ring stroke/will move in a horizontal line, 1201:

which is that most effective for Yperforming properly the raking, action. At. the end .of the forward A.raking 'stroke 'the bars. will move upwardly slightly so that the rake teeth will deliver the gathered hay to the 25 elevator frame, whereupon the bars @will move in their return stroke rearwardly in adownward curve.

We believe ourselves to be the first to provide for a movement of the rake bars rela 180 iis y tive to the opera-ting levers, by means controlled by-the operation of the'levers, and to this construction it is our intent iii the appended' claims .to lay broad claim. It is manifest, however, -that the details of construction for effecting this result may be variously changed and modifieduwithout departing from the spirit of the invention, and it will be'nnd'erstood that the invention is not limited to any particular form or construction of the parts except in so `far as such limitations are specified in the claims. l Having thus described our invention,

what 'we claim is: f 1. In a hay loader, the combination oi an elevator frame, raking devices coperating therewith, operating levers for the raking devices, means for operating said levers, and members connecting the operating le- 2e vers with the raking devices and constructed to permit of a movement' of the raking devices relative tothe levers in the direction of the raking stroke of the devices, said members being controlled by the levers and acting when the levers are operated to shift the raking devices relative to the levers in. the direct-ion of the raking stroke of the raking devices. 2.
